Using JungleDisk, a free app for Windows and Mac, Matt mounts his S3 drive on any 'net-connected computer and listens away. This seems like a good solution for those who don't want to stream iTunes from their home computer, but as Matt says, streaming tunes over the 'net can "make your music may not sound as 'immediate' as if it was on your local hard drive." Anyone out there using S3 for backup for media storage? Tell us what you think about it in the comments.
